TYPE-WRITER CABINET.

SPECIFICATION forming as of Letters Patent No. 765,076, dated July 12, 1904.

Application filed March 3, 1904- Serial No. 196.278- (llo model.)

To all whom it may concern.-

Be it known that 1, WILLIAM HORROCKS, a citizen of the United States, and a resident of Herkimer, in the county of Herkimer and State of New York, have invented a new and useful Improvement in Type-Writer Cabinets, of which the following is a specification.

This invention relates to that class of typewriter cabinets or desks which are provided with a movable platform upon which the type writer is mounted and with a top or cover which can be pushed backwardly and downwardly into the cabinet when the type-writer is to be used.

My invention has particular, reference to a cabinet in which the top and platform are not connected by mechanism in such a way that the movement of the platform is positively effected by the movement of the top in either direction, but in which the platform is disconnected from the top and the lowering of v the platform is effected by gravity.

The object of the invention is to produce a simple and convenient mechanism of this kind.

In the accompanying drawings, Figure l is view showing the platform in its horizontal operative position and the top in its lowered position: Fig. 3 is a fragmentary vertical section at right angles to Fig. 1 in line 3 3, Fig. 1, on an enlarged scale. Fig. 4 is a sectional view, on an enlarged scale, of the adjustable platform-support inlinef- 4, Fig. 1. Fig. 5 is a view similar to Fig. 4, showing a modified construction of the adjustable platformsupport. Fig. 6 is a cross-section in line 6. 6., Fig. 5.

Like letters of reference refer to like in the several figures.

A represents one of the side walls, A the rear wall, and A the fixed rear portion of the top of a type-writer cabinet.

B represents the movable top, which is arranged, as usual, to rest in its normal horizontal position upon ledges on the side walls parts of the cabinet and to extend to the fixed rear.

portion A of the top.

(1 represents the movable platform or shelf upon which the type-writer is mounted.v The movable top is not connected with the platform,but 'is connected at each side to the adjacent side wall of the cabinet by a front link D and a rear link I). The link D is pivoted at its rear end-to the cabinet-wall by a pivot 11, and the link D is pivoted at itslower end to the wall by a. pivot d. connected at each side to the adjacent side wall of the cabinet by a bent rock-arm E, which is pivoted to the cabinet-wall at its lower or front end bya pivot e. The platform is attached to these arms in such manner that its position can be adjusted toward and from the pivots of the arms, thereby raising or lowering the platform when in its horizontal or operative position. This adjustment is resorted to for rendering the position of the machine convenient for. the operator-for instance, for adjusting the platform to the height or size of the type-writer-the platform being lowered for a large machine and raised for a small machine. The specific adjusting devices a shown in Figs. 1 to 4 of the drawings consist of a longitudinal slot f, formed in the straight portion of the arm'and an attaching-bolt f, passing through this slot and through a bracket f secured to the under side of theplatform. In the construction shown in Figs. 5 and 6 the arm E and bracket f are secu red together by slidable dovetails f and a set-screw f. The bent form of the adjusting-arms provides for a comparatively long adjustment of the platform on the arms without increasing the effective length of the arms.

G represents a horizontal-shifting-bar, which is arranged on the inner side of the side wall of the cabinet and connected at its front end by a pivot g to the free end of the bent arm E and supported near its rear end by a pendent link H, which is pivoted at its upper end It to the side wall of the cabinet. The rear end of this shifting-bar stands in such a relation to the movable top B that when thelatter is moved backwardly and downwardly into the cabinet the under side of the top strikes against the rear ends of these shifting bars and pushes the bars forwardly, thereby raising the platform to its horizontal position,

While it may be desirable in most cases to connect the platform to the oebinet at a short distance in reer of the root end oi? the pletiorm, es showm in order to project the pleir form forwardly when raising: it to opera tive position, this style of connection is not indispensihie, and other volt-knowstyles by which the pietform is not moved forwardly may be er'npioyed if desired, Various other modifioetions of speeifie deteiis may also he made without departing from the essentiai features of the invention;
